HP Prime problem. Calculator resetting itself

[Michael K-K]

I now downgraded back to 8151 and the Prime is stable again.
Before that I tried the new method for installing the latest firmware which went fine. At first the calculator seemed stable, but after a while it crashed repeatedly and at random and then every time I tried to reach home from CAS.

Dear Tim,
in case this is interesting enough to look into it just let me know what information i can provide.

Thanks for the help.

Michael
